Description

The base class of the Gtk+ type hierarchy.

  • Each widget is a represented as a purely abstract data type. It can only be accessed through and the special access functions that are defined in each widget file.
Synopsis
data Object
class GObjectClass o => ObjectClass o
castToObject :: GObjectClass obj => obj -> Object
toObject :: ObjectClass o => o -> Object
makeNewObject :: ObjectClass obj => (ForeignPtr obj -> obj) -> IO (Ptr obj) -> IO obj
Detail
Object is the base class for all widgets, and for a few non-widget objects such as Adjustment. Object predates GObject; non-widgets that derive from Object rather than GObject do so for backward compatibility reasons.
